A true technological marvel, a self-winding mechanical watch draws its energy from the movements of the wrist: that’s what makes this high-end timepiece so magical. So when it’s not being worn, it can quickly lose accuracy. Combining refined design with technical innovation, the Masterbox Carbon Fiber 1 watch winder simulates wrist movements to keep your automatic watch running and thus keep it accurate—an essential accessory for watch enthusiasts.
